PHP Twitter API problems?

Question

A site I manage uses the my_twitter.php class simply to receive tweets from one certain account. As of a few hours ago this has stopped working, it displays a wrong username / password message while the credentials are correct.

On various websites I am reading about API problems but I'm not sure if the my_twitter class needs to be replaced with another one that uses OAuth, or will the problems be resolved and my_twitter start working again? That class is still listed as an official library by Twitter.

EDIT: turns out I do not need OAuth to just receive the latest tweet. http://dev.twitter.com/doc/get/users/show This link explains things well

Answer 1

Quote from twitter received email:

Some applications you have been using may require you to reauthorize them or may stop functioning at the time of this change.

Answer 2

This is from an email I received from Twitter this morning, titled 'Update: Twitter Apps and You':

Update 1: New authorization rules for applications

Starting August 31, all applications will be required to use “OAuth” to access your Twitter account.

What's OAuth?

• OAuth is a technology that enables applications to access Twitter on your behalf with your approval without asking you directly for your password.
• Desktop and mobile applications may still ask for your password once, but after that request, they are required to use OAuth in order to access your timeline or allow you to tweet.

What does this mean for me?

• Applications are no longer allowed to store your password.
• If you change your password, the applications will continue to work.
• Some applications you have been using may require you to reauthorize them or may stop functioning at the time of this change.
• All applications you have authorized will be listed at http://twitter.com/settings/connections.
• You can revoke access to any application at any time from the list.application at any time from the list.

So it does look like you need to find another library, that uses OAuth.
